  • the visual alert may specify the amount of time before the portable electronic device 100 enters the restricted mode, or it may specify what vehicle action will trigger the portable electronic device 100 to enter the restricted mode.
  • vehicle actions may include starting the vehicle, engaging the transmission or moving the vehicle.
  • a portable electronic device 100 that is located outside the BAN will be fully operational. For example, any passenger in the vehicle may use a portable electronic device 100 while the vehicle is in operation.
  • Any portable electronic device 100 within the BAN will receive the signal and operate to restrict functionality will the driver is operating the vehicle. For example, if the driver holds a passenger's portable electronic device 100 while operating the vehicle, and the passenger's portable electronic device 100 includes the receiver 70 described above, the functionality of the passenger's portable electronic device 100 will be restricted whilst in the possession of the driver 90.
  • the vehicle device 80 may have multiple transmitters and/or transceivers located near every vehicle occupant, including both the driver and passengers.
  • Figure 9 illustrates transmitters 82d, 82e, 82f, and 82g underneath each of the seats in the vehicle.
  • the vehicle device 80 will be programmed with a plurality of modes that it may send to the one or more portable electronic devices 100 located in the vehicle. Different restricted modes will be sent to the portable electronic devices 100 of different occupants.
  • the modes may be classified as driver modes (D-mode) and passenger modes (P-mode), and there may be multiple modes for each classification.
  • the passenger modes will typically include minor restrictions, such as disabling any camera on the portable electronic device 100.
  • the use of particular modes allows the selective restriction of functionality of portable electronic devices 100 to be used in restricted areas, such as military bases, for all vehicle occupants.
  • the table below illustrates example driver modes and passenger modes and the corresponding functionality of the portable electronic device 100 that is disabled. Where there is a 'Y' in the table, the corresponding functionality is disabled. Where there is a 'N' in the table, the corresponding functionality is still enabled and may be used by the user.
  • the restricted mode D-mode 1 will disable all functionality of the portable electronic device 100 except for emergency calls and voice activated calls.
  • P-mode 1 will disable only the camera and IM functionality of the portable electronic device 100.
  • the table is illustrative only and additional functionality of the portable electronic device 100 may be enabled or disabled according to a particular restrictive mode.
  • the portable electronic device 100 remains in the restricted mode while it continues to receive the BAN signal from the vehicle device 80.
  • the receiver 70 on the portable electronic device 100 polls periodically to determine whether it is still receiving a BAN signal from the vehicle device 80. The polling may be performed according to a predetermined duration, such as every few seconds to see whether it is receiving the BAN signal. If the portable electronic device 100 is still receiving the BAN signal, then the portable electronic device 100 remains in the restrictive functionality mode. If the portable electronic device 100 polls and no longer detects the BAN signal, then the device is out of the range of the BAN. Once out of range of the BAN signal, the portable electronic device 100 returns to normal operation.
  • the BAN signal may be transmitted through the transmission medium, a biological body (driver 90), using an electromagnetic signal instead of a capacitive signal.
